Portable (suitcase) solar "install" question
I've gone back and forth on solar panels on the roof or portable. Well, due to a tight budget, portable is the only way I'm going to get solar for now and it makes sense for me to try it out 1st as we...

Here is what Specialty Concepts has to say about that. Note they specify the voltage drop controller to battery be no more than 1/4 volt but that you can have 1/2 volt controller to panel.
"result in a voltage loss that will cause the batteries to be under-charged and/or
result in excessive heat at the connection. A poor connection to the battery will
also distort the battery voltage reading and cause the charging to stop too soon.
To check the connections, a voltage multi-meter is required and the ASC must be
charging with maximum expected charge current (very sunny conditions).
Battery Connection: - First, note the voltage at the battery terminals. Select the
positive and negative terminals that are used for the ASC connection. Then,
immediately check the voltage at the ASC terminals for “BATT (+)” and “BATT (-
)”. The difference in voltage should not be more than ¼ volt*.
Array Connection: - Next, note the voltage at the panel wires. Select the
positive and negative wires that are used for the ASC connection. Then
immediately check the voltage at the ASC terminals for “ARRAY (+)” and
“ARRAY (-)”. The difference should also be no more than ½ volt*."
